The Smartest Man In The World

There were 3 people in a crashing plane, the smartest man in the world, the president of the USA, and a little girl. There were only two parachutes. The smartest man in the world stood up and said, "The people who would benefit the world the most should be the ones who get the parachutes and I being the smartest man am one of those." With that he grabbed one and jumped out. The president looks at the little girl and says "I've led a good long life, you take the last parachute." And the little girl replies, "Don't worry, we can both have one, the smartest man in the world just jumped out with my backpack."
